Thanks. A couple of issues:

* It should be the LTR environment, not RTL, right?

* I don't like the hardcoding of insets. Basically, this is needed will
all "display" insets, right? And it will break with "inline" listings
(\lstinline), which shouldn't go on an own line

I in order to properly support that we need to introduce an
Inset(Layout) tag that indicates whether an inset starts a new
paragraph in the output (we have a half-implemented isDisplay() member
in InsetLayout, but IIRC this has a different semantics, only referring
to whether it stands on a new line in the code)

This needs some effort. For the time being, I think we will be better
off with this rather harmless info message.
